Guile Reference Manual
20.4 Reference Material Layout
This part of the reference manual documents all of Guile's core
Scheme-level language and features in functionally-related groups.
Where a particular section of the manual includes both R5RS-compliant
parts and Guile-specific extensions, the text indicates which parts of
the documentation describe R5RS behaviour and which parts describe Guile
For a quick way of identifying the parts of Guile that implement
R5RS-compliant features, see the R5RS index: R5RS Index.
